Products Power Conversion Engineering Precision-engineered AC/DC wall-mount adapters, linear transformers, and high-density switching power supplies qualified for tactical communication, rugged mobile units, and industrial infrastructure.
From standard off-the-shelf modules to fully customized military-spec power systems, our Exeter, New Hampshire engineering team delivers uncompromised reliability across terrestrial, naval, and aerospace operational theaters.
Our custom defense-grade converters and power assemblies are built to meet or exceed rigorous standards including MIL-STD-1275 (vehicle transient surge protection), MIL-STD-461 (EMC/EMI emissions suppression), MIL-STD-810 (environmental shock, vibration, and humidity), and MIL-STD-704 (aircraft power characteristics).
To compress qualification lead times and minimize non-recurring engineering (NRE) costs, we specialize in modified-standard adaptations—adjusting output voltage trims, heavy-duty potted enclosures, conformal coating, connector harnesses, and thermal baseplate derating while preserving pre-qualified safety topologies.
Defense platforms require service lifetimes extending 15 to 30 years. We mitigate Diminishing Manufacturing Sources and Material Shortages (DMSMS) by providing exact form-fit-function legacy replacements and guaranteeing long-term production release continuity without forcing complete system redesigns.
An in-depth analysis of architectural shifts in defense energy conversion, SWaP-C optimization, and semiconductor innovation for tier-1 defense contractors and military OEMs.
The military power electronics sector is experiencing a paradigm shift from traditional Silicon MOSFETs to Gallium Nitride (GaN) and Silicon Carbide (SiC) switching components. Wide-bandgap (WBG) semiconductors operate at dramatically higher switching frequencies with reduced parasitic capacitance. This technological breakthrough reduces passive component size (inductors, transformers, and capacitors) by up to 45%, achieving unmatched power density (>100W/in³) essential for airborne radar, unmanned aerial vehicle (UAV) payloads, and compact soldier-worn power distribution hubs.
Rotational fans represent a critical single point of failure in combat environments, vulnerable to dust, sand ingress, moisture, and acoustic detection. Modern military power designs prioritize high-efficiency conduction-cooled baseplates and hermetically sealed potted enclosures. By employing advanced metal-core PCBs, synthetic diamond thermal interfaces, and direct-to-chassis heat dissipation pathways, modern tactical power units maintain 100% full-load output under extreme ambient temperatures ranging from -55°C to +125°C without requiring forced air ventilation.
Size, Weight, Power, and Cost (SWaP-C) constraints dominate modern defense procurement specifications. As ground combat vehicles, naval surface vessels, and mobile command shelters are equipped with increasingly dense C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance) electronics, power converters must deliver higher wattages within scaled-down physical envelopes. The industry trend favors scalable brick architectures (Quarter-Brick, Half-Brick, Full-Brick) with integrated planar transformers that offer low profile heights (<12.7mm) and extremely high power efficiency exceeding 95%.

Insights into how defense logistics agencies, prime contractors, and international military exporters are adapting their supply chain and specification strategies.
Traditionally, military procurement relied almost exclusively on custom-designed power supplies developed over multi-year development cycles with high non-recurring engineering (NRE) costs. Today, global defense procurement officers are prioritizing Military Commercial-Off-The-Shelf (COTS) and Modified-COTS power solutions. By starting with proven, field-tested catalog platforms—such as high-density AC/DC converters or wide-input DC/DC modules—and modifying mechanical enclosures, potting compounds, or pin configurations, defense programs achieve compliance 60% faster while reducing upfront development expenditure by up to 70%.
Geopolitical volatility and international logistics disruptions have exposed severe vulnerabilities in cross-border defense supply chains. Major defense procurement organizations across North America, NATO alliance nations, and allied defense exporters are strictly enforcing sourcing transparency. Preference is given to suppliers with established domestic engineering centers (such as US-based R&D facilities), verified component traceability protocols, anti-counterfeit protection policies, and multi-tier supplier redundancies to safeguard critical program timelines.
Tactical forward operating bases (FOBs) and modernized armored combat vehicles are rapidly transitioning toward hybrid-electric propulsion and micro-grid energy architectures. This shift requires bi-directional DC/DC converters, high-voltage input power supplies (accepting 110VDC, 280VDC, or 310VDC buses), and active power factor correction (PFC) front-ends capable of operating seamlessly off erratic tactical generators, solar arrays, or vehicle alternator buses. Power supplies are no longer standalone adapters; they are fully integrated intelligent energy node management components.
Direct technical answers to standard engineering and sourcing inquiries encountered during defense program qualification.
Our military power conversion platforms are engineered to meet key defense standards upon request. This includes MIL-STD-1275A/B/C/D/E for 28V DC electrical systems in military ground vehicles (providing immunity against 100V surges and 250V spikes), MIL-STD-461E/F/G for electromagnetic compatibility and EMI suppression (conducted and radiated emissions), MIL-STD-810G/H for environmental conditioning (extreme shock, vibration, altitude, salt fog, and fungus), and MIL-STD-704A-F for aircraft electric power characterization.
A Modified-Standard power supply utilizes an existing, field-proven catalog circuit topology and modifies specific parameters such as output voltage trimming, cable harness connectors, thermal baseplate geometry, environmental potting, or custom screening. This approach dramatically shortens lead times and qualification costs. A Fully Custom design starts from a clean sheet based on your exact electrical, mechanical, pinout, thermal, and compliance specification, engineered from the ground up when standard off-the-shelf geometries cannot fit your enclosure.
We utilize advanced conduction cooling methodologies, planar magnetic designs, and high-thermal-conductivity encapsulation compounds (potting). Heat generated by active switching components is transferred directly through low thermal-resistance interfaces to an integrated aluminum baseplate or cold-plate system. This allows fanless operation across extreme ambient temperature ranges from -55°C to +125°C, eliminating mechanical moving parts that fail in harsh, dusty, or high-vibration tactical environments.
We provide ultra-wide DC/DC input ranges, including 4:1 and 8:1 wide input windows. For military ground vehicle systems, our converters accommodate nominal 28VDC inputs with operating ranges spanning 9VDC to 36VDC (and transient surge capability up to 100VDC). For naval and high-voltage DC buses, we manufacture converters designed for nominal 110VDC, 270VDC, and 310VDC distribution networks.
Yes. Defense programs frequently remain active for 15 to 30 years. We specialize in form, fit, and function replacement solutions for obsolete or end-of-life (EOL) third-party power supplies. Our commitment to obsolescence management ensures long-term manufacturing support, preventing an EOL component in your bill of materials from forcing an expensive redesign of your entire mission system.
